Title: Method for homogenising dust falling in amounts more or less separate from one another and apparatus for carrying out the method
Inventor: STRAUSS UDO DR PHIL
IPC: F23K3/02
Filed: 1981-04-09
Abstract: In some dust removing apparatuses, dust falls downwards in amounts more or less separate from one another, which can result in difficulties at subsequent processing stages. In order to homogenise the falling dust, in particular coal dust falling into a blow injector, along a dropping stretch the dropping paths of the grains of dust at least of a partial amount of each separate amount are lengthened relative to the remaining amount such that essentially the gaps between the remaining amounts are filled. In an apparatus for carrying out the method, a homogenising assembly (20; 21) having at least one guide vane inclined with respect to the direction of flow is provided in a downpipe (5) enclosing the falling dust. <IMAGE>

Title: Vertically arranged plate electrode for gas-forming electrolyser
Inventor: LOHRBERG KARL
IPC: C25B11/02
Filed: 1981-06-15
Abstract: In gas-forming electrolysis devices, in particular membrane electrolysers, the removal of gas presents difficulties, particularly with a close electrode spacing. However, for energy consumption reasons, a close electrode spacing is desirable. As a remedy, electrode plates to be arranged vertically in gas-forming electrolysers have already been provided with horizontally and continuously extending plate gaps and with guidance devices in the region of the gaps for removing the gases evolved. In order to avoid energy losses and to ensure rapid gas removal, in a device of the type mentioned, the entire active electrode surface of the individual electrode plate is, according to the invention, arranged parallel to, and at the shortest spacing from, the counterelectrode and the guidance device is angled at the respective upper edges of the plates of the counterelectrode.

Patent DE-3138664-A1 (DE)
Title: Label feeding device
Inventor: BUCKERT GUSTAV
IPC: B65B13/18
Filed: 1981-09-29
Abstract: The invention relates to a label feeding device on strapping machines, comprising a magazine which contains the labels in compartments or holders while at the same time forming interspaces. After every automatic removal of a label by means of a push-out ram, the magazine must be further displaced by a step so that the next label is situated in front of the push-out ram. The step-by-step advancing of the magazine must be very accurate, because otherwise the errors sum up and the ram no longer strikes the thin label. An accurate step-by-step advancing of the magazine is achieved according to the invention in that for each step a ball or roller is fed to a channel by means of a drive, the first ball or roller driving the magazine via a driving element which projects into the channel. The balls or rollers are dimensionally very accurate since they originate from rolling bearing mass production.

Patent DE-3204684-A1 (DE)
Title: Water heater
Inventor: KUEMMERLE BRUNO
IPC: F24H4/04
Filed: 1982-02-11
Abstract: A water heater for connection to a heat-pump installation is proposed, in which the storage container contains an upper service water accumulator and a lower buffer accumulator which are separated from one another by a partition and contained in a common housing. The buffer accumulator can be connected to a heating installation. It contains on the inside a condenser, or at least condenser section, conducting working medium of the refrigerating circuit. The partition forming the bottom of the service water accumulator is designed as condenser therefor and connected in series to the condenser section of the buffer accumulator, in front of the latter. A condenser section situated inside the service water accumulator is also possible, which condenser section is connected in series to that of the buffer accumulator or to its own separate refrigerating circuit. Service water heating by heat transfer from the buffer accumulator alone is also possible. By combining buffer accumulator and service water accumulator in one housing, the space requirement and the costs for the buffer accumulator are reduced significantly.
Patent DE-3207357-A1 (DE)
Title: Method and device for measuring the flow in open channels, particularly those carrying waste water
Inventor: PROKEIN JOSEF
IPC: G01F1/00
Filed: 1982-03-02
Abstract: As a departure from the known fixed arrangement at the bottom of the channel, to measure the flow in open channels the flow meter is arranged so that its height can be adjusted with the waste water level. To determine the throughput, the height of the waste water level and the flow rate are measured. Since the cross section of the open channel is known (for example, it has a rectangular cross section), the throughput is obtained by a simple mathematical method.
Patent DE-3208392-A1 (DE)
Title: Ventilating appliance for ventilating and venting rooms
IPC: F24F12/00
Filed: 1982-03-09
Abstract: The appliance operates on the principle of decentralisation. A ventilating appliance is to be available for each room or for each workplace, so that account can be taken of individual requirements. The ventilating appliance is to be favourably priced and space-saving, but especially is to operate in a strongly sound-damping and energy-saving fashion. Accordingly it is characterised by air guiding channels which run essentially diagonally, with the ventilating appliance consisting internally of an upper part and a lower part which are made of a partially flexible, vibration-damping and sound-damping material. Metallic or non-metallic cover plates are provided in the outer region, and in fact these are especially the cover surface (25) and the floor plate (49). Moreover, the front and rear sides are covered with such plates with corresponding openings. <IMAGE>
Patent DE-3209176-A1 (DE)
Title: Mobile device for mechanical closing and opening of pipeline slide valves
Inventor: PREUSS ERICH
IPC: F16K31/05
Filed: 1982-03-13
Abstract: In order to reduce the manual force and time consumption, which are often relatively large, for operating pipeline slide valves, the conventional slide valve is converted into a slide valve which can be operated mechanically, with a small amount of re-equipment. To this end, the handwheel which is now present on the slide valves is replaced by a handy gearwheel and a pinion bolt guide seat is constructed or fitted to the slide valve. In the case of slide valves which are installed in the ground, the spindle extension is held by a guide in the road cap, on which the bolt guide seat is located, in order to ensure a correctly fitting seat. In this case, a quadrilateral protector with a rod which passes through the gearwheel whose height is adjustable is placed on the spindle extension instead of the slide valve key. The adjustment capability is necessary as a result of the different spindle extensions. After fitting the gearwheel, or the stationary existing gearwheel, the pinion which is clamped into the drive machine is inserted with its bolt into the guide seat, such that it forms a fit with the gearwheel. The drive machine is now set in motion to the right or left in order to close or open the slide valve.

Patent DE-3224492-A1 (DE)
Title: Fish-hook
IPC: A01K83/06
Filed: 1982-06-28
Abstract: In fish-hooks known as three-pronged hooks, having two catching hooks and an attachment hook for a bait fish, the problem exists that, after the attachment hook has been pushed into the region of the dorsal fin of a bait fish, the two catching hooks project laterally from the body of the bait fish, so that the fish to be caught can strike the bait fish but releases the latter again, because of this, immediately after the strike. In order to ensure that the fish to be caught swallows the bait fish together with the fish-hook, without noticing anything of the presence of the fish-hook, the invention provides that the attachment hook and the associated shank are arranged in a plane aligned transversely to the medium plane of projection between the shanks of the two catching hooks and that the shank of the attachment hook is aligned transversely to the shanks of the catching hooks. After the insertion of the attachment hook into the region of the dorsal fin of the bait fish, the two catching hooks with their associated shanks come to rest on the body of the bait fish, on both sides thereof, so that the fish to be caught, on attacking and swallowing the bait fish, does not notice the presence of the fish-hook during the strike. A substantial increase in catch rates is thus guaranteed.

Patent DE-3235209-A1 (DE)
Title: Clamp
Inventor: GORSKI WILFRIED
IPC: B63B35/79
Filed: 1982-09-23
Abstract: In a clamping holder which serves to firmly clamp the sheet of a sail of a windsurfing appliance and through the body of which the sheet end hanging down is pulled and in which the sheet can be firmly clamped, reliable clamping of the sheet in the face of greater tension from the sail of the windsurfing appliance is not guaranteed, and actuation of the sheet during sailing in order to change the at first bulbous sail, for example, into a flat sail as a result of changed wind conditions is made more difficult. In order to ensure in the case of a clamping holder that the sheet is firmly clamped even in the face of greater tension from the sail and to make possible easier actuation of the sheet during sailing, a rolling body transversely overlapping the sheet part located in the clamping holder is mounted in two elongated holes in the wall of the clamping-holder body, and the lateral boundaries of the elongated holes form planes sloping away towards the sheet part located in the clamping holder.
